To'all whom it may concern: l Be it known that I, O'r'ro J. G'ROEHN, a

citizen of the United States of American:

. ing is a specification, reference being had therein to the accompanying drawings.

This invention relates to torch burners and refers more particularly to a new and improved construction adapted for blow torches or the like.

Among the objects of the invention are to provide a torch having a more efficient combustion chamber'than those now in use; to provide a torch in which the liability of the torch to produce incomplete combustion is minimized and in general to provide a new and improved torch burner of the character above mentioned. The invention also re. sides in the novel arrangement of the top deflecting wall or plate and in such further features of construction and arrangements and combinations of parts as will more fully hereinafter appear.

In the drawings:

Figure 1 is a top plan view of a torch embodying my invention; I

Figure 2 is a vertical cross-sectionon the line 2-2 of Figure 1.

Describing in detail the particular embodiment of my invention shown in the drawings, A designates a torch burner which is provided at its side with a fitting A whereby it is supported by a pipe or stand-- ard A upon the tank A In blow torches of this general character means is provided for forcing the fuel from the tank out of a discharge orifice toward or into a combus tion chamber and the present invention relates primarily to the burner construction.

Describing now in detail the burner B designates a preheating chamber in which the fuel coming from the tankA through the pipe A is first preheated before passing the control Valve 0. In order to get from 1 the chamber B to the port C it is necessary for the fuel to pass through the tube B and thus be carried adjacent the lower wall of the combustion chamber D and from here the fuel passes through the port C, passageway E through the discharge nozzle E. The latter is preferably carried by a removable fitting E and an adjustable member F is WIDE-MOUTH TORCH BURNER.

Specification of Letters Patent. I June 27 1922 1 normally out} I. nozzle E. but:

adapted when adjusted forwardto'cleanany carbon'or otherobstruction which might ac- A 60,-

cumulate on the discharge nozzle After passing from the discharge nozzle the fuel mixed [with the air isforced'in to" the chamber in which-combustion takes place and 1t is the primary object of this invention to provide a new and improved construction and arrangement of combustion chamber. As shown in detail in F igure 2, the combustion chamber D has its top wall G provided with a downwardly inclined portion G against which the fuel discharge from the nozzleE, strikes. This not only provldes a hot spot or surface which will insure combustion but it also forces the hot gases down against the lowerrwa'll G of the combustion chamber and thereby greatly increases the vaporizing effect ofthe fuel coming throu h the preheating chamber B and its tube It willalso be noticed that the combustion chamber D flares outwardlyin a forward directionand terminates in a portionI-I having substantially parallel walls H. By this arrangement a I flame of any desired width orshape can be I obtained, the particular shape shownin the drawings being particularly adapted for nature.

While I have shown the downwardly in-.

clined wall G as being used inficonnection with a wide flattype of'dischar'ge outlet,

in the broader aspects the invention isnot limited to the use of this feature with the '95 I particular novelty shown and various other changes can be made" without departing from: the spirit ofmy invention. 7

What I claim as my invention is 1. In a blow torch, a burner comprising; f

a discharge orifice, a combustion-chamber located'in advance of sald orifice, said combustion chamber havlng a downwardly and forwardly inclined wall and having forwardly and outwardly inclined side walls.

2. In a blow torch, a burner comprising a discharge'orifice, a combustion chamber located in advance of said orifice, said combustion chamber having a downwardly and forwardly inclined wall and having forwardly and outwardly inclined sidewalls terminating at the extreme forward end in substantially parallel side walls.

3. In a blow torch, a burner comprising a discharge orifice, a combustion chamber located in advance of said orifice, a pre-heat ing chamber located beneath the center of the combustion chamber, and means for directing the hot gases of combustion against one wall of said combustion chamber adjasaid combustion chamber, valve controlled means extending from the preheating chamber for supplying a fuel to the orifice,

and means for deflecting the hot gases of combustion against one wall of said combustion chamber adjacent to the forward end of the pre-heating chamber.

5. In a blow torch, aburner comprising a discharge orifice, a combustion chamber located in advance of said orifice, a preheating chamber adjoining said combustion chamber, and a conduit in said preheating chamber adjacent to one wall of said combustion chamber and in communication with said discharge orifice, said combustion chamber having means for deflecting the heat against the Wall thereof adjacent to I said conduit.

In testimony whereof I affix my signature.
